The young Manhattan woman mowed down by a garbage truck Thursday night had just graduated college a week ago, her heartbroken family said yesterday.

Wynee Wong, 21, had come back to her proud parents’ Pearl Street apartment after getting her sheepskin from prestigious Bucknell University in Lewisburg, Pa., and was looking to pursue a career in law.

“She was an honor student, a beautiful person,” said Wong’s mother, who declined to give her name.

The grieving mother said her daughter was a good girl who was always home by 10:30 p.m. and if she was ever running late, she’d call to let her know.

“This is so awful,” the mother said. “She doesn’t deserve this.”

A privately owned sanitation truck plowed into Wong, 21, around 9 p.m. Thursday as she was crossing the Bowery. The truck had been heading east on Bayard Street and slammed into her as it made a right turn. The young woman was pronounced dead on arrival at Beekman Hospital.

The driver wasn’t charged and police did not identify him.

The Wong family has retained an attorney and may sue. “Maybe that truck wouldn’t have hit her if the driver were going more slowly. That driver is to blame,” Wong’s mother said. “He should take responsibility.”
